Definitions

  • Inkjet printing is a non-impact printing method that utilizes electronic signals to control and direct droplets or a stream of ink to be deposited on media.
  • Some commercial and industrial inkjet printers utilize fixed printheads and a moving substrate web in order to achieve high speed printing.
  • Current inkjet printing technology involves forcing the ink drops through small nozzles by thermal ejection, piezoelectric pressure or oscillation onto the surface of the media. This technology has become a popular way of recording images on various media surfaces (e.g., paper), for a number of reasons, including, low printer noise, capability of high-speed recording and multi-color recording.
  • FIGs. 1 A and 1 B depict an area-fill print for an example of the liquid ink disclosed herein and an area-fill print for a comparative ink (respectively) after nozzles up capped storage;
  • FIG. 2A depicts an area-fill print for an example of the liquid ink disclosed herein after nozzles down capped storage;
  • Figs. 2B and 2C depict area-fill prints for two comparative inks after nozzles down capped storage;
  • Figs. 3A and 3B depict microscopic images of printhead nozzles after oven storage containing an example of the liquid ink disclosed herein and a comparative ink (respectively) and after wiping and imaging; and
  • FIGs. 4A and 4B depict a nozzle health pattern for an example of the liquid ink disclosed herein and a nozzle health pattern for a comparative ink (respectively).
  • wax emulsions may be added to thermal inkjet inks to improve the durability of the resulting print film.
  • wax emulsions may improve the abrasion resistance of the resulting print film.
  • incorporating wax emulsions into thermal inkjet inks may lead to complications with thermal inkjet print nozzle health and reliability. For example, the presence of a wax emulsion in a thermal inkjet ink may cause clogging of manufacturing filters and printer filters.
  • Clogged filters may restrict the ink flow rate and cause a pressure drop on the back end of the filter.
  • the presence of a wax emulsion in a thermal inkjet ink may also cause the formation of agglomerates in printhead nozzles.
  • the agglomerates may be formed from wax particles, either alone or in combination with colorants (e.g., pigment particles). Whether agglomerates form when printheads are stored nozzles down or nozzles up may depend on the specific gravity of the wax particles. When printheads are stored nozzles down, wax particles with a higher specific gravity may settle and form agglomerates in the nozzles. When printheads are stored nozzles up, wax particles with a lower specific gravity may cream (float upwards) and form
  • thermal inkjet printhead nozzles are heated and exposed to air, which can cause the evaporation of volatile ink
  • a liquid ink which may be digitally printed with a thermal inkjet printhead on a substrate.
  • the liquid ink includes a polytetrafluoroethylene (PTFE) wax emulsion.
  • PTFE polytetrafluoroethylene
  • an over-print varnish which may be digitally printed with a thermal inkjet printhead on a substrate, and which includes the PTFE wax emulsion.
  • the PTFE wax emulsion includes a PTFE wax which has a particle diameter that is less than 50 nm. Incorporating the PTFE wax emulsion, including the PTFE wax with a particle diameter less than 50 nm, in the liquid ink or the over-print varnish improves the health and reliability of the thermal inkjet print nozzles that are dispensing the liquid ink or the over-print varnish. For example, the incorporation of the PTFE wax emulsion into the liquid ink or the over-print varnish may lead to improved filterability, reduced agglomerate formation, and improved agglomerate recoverability in thermal inkjet print nozzles.
  • liquid ink and the over-print varnish may each be reliably printed (even though each includes a wax emulsion) because of the chemical structure and particle diameter of the PTFE wax used in the PTFE wax emulsion.
  • the PTFE wax does not cream like other comparable waxes (e.g., polyethylene waxes).
  • the liquid ink or the over-print varnish, including the PTFE wax emulsion is less likely to form agglomerates in printhead nozzles when the printheads are stored nozzles up (as compared to other comparable inks including other waxes, e.g., polyethylene waxes).
  • the PTFE wax also has higher melting and softening points than other comparable waxes (e.g., polyethylene waxes).
  • the higher melting and softening points of the PTFE wax make it less likely that the PTFE wax will break from its emulsion during thermal inkjet printing, when the thermal inkjet printhead nozzles are heated and exposed to air.
  • the liquid ink or the over-print varnish, including the PTFE wax emulsion may have reduced agglomerate formation in thermal inkjet printhead nozzles during printing and may also be less likely to form agglomerates that are difficult to remove with servicing (as compared to other comparable inks including other waxes, e.g., polyethylene waxes).
  • the PTFE wax particles having a particle diameter that is less than 50 nm also settle slower than PTFE wax particles with a larger particle diameter. Thus, fewer agglomerates may be formed when the printheads are stored nozzles down.
  • the PTFE wax having a particle diameter that is less than 50 nm may also be less likely to clog filters than a PTFE wax with a larger particle diameter. Thus, the filterability of the liquid ink or the over-print varnish may be improved (over similar inks, including waxes with larger particle diameters) by incorporating PTFE wax having a particle diameter that is less than 50 nm.
  • the PTFE wax having a particle diameter that is less than 50 nm may allow for a reduction in the amount of the PTFE wax emulsion that would otherwise be incorporated in the liquid ink or the over-print varnish in order to achieve a threshold level of print film durability.
  • the particles of the PTFE wax have a large surface area to weight ratio, such that there is more coverage of the PTFE wax in a print film than there would be with a larger particle diameter at an equivalent weight (or % actives). It is believed that the greater coverage of the smaller PTFE wax particles in the print film leads to better and more consistent durability.
  • a higher weight percentage of the particles may have to be used (e.g., greater than 1 % actives).
  • a higher weight percentage of larger particles can deleteriously affect the jetting reliability.
  • the reduction in the amount of the PTFE wax emulsion in the liquid ink or the over-print varnish e.g., to an amount ranging from about 0.25% actives to about 1 % actives
